' UNITED sTATns v JACOB D.1YOLF,-( )F Lonnoigiiivetann. SEPARATION or wraps rnom rnnm ones. I :1 i 7 To all whom it may concern:

Be it known that L'Jscon DAVID WOLF, a citizen of the United States of America, residing at 17 Throgmorton avenue, in the city of London, England, have invented certain new and useful Improvements in'the Sepa ration of Metals from Their Ores, of which the following is a specification.

This invention has for its object improvements relating to the separation of metals from their ores by the employment of oil or grease having a high degree of viscosity and cohesion. I employ oil or grease, which has been treated with chlorid of sulfur or other suitable material, to alter its physical characteristics or otherwise render it suit able for use in conjunction with an apparaing motion is imparted by any suitable means which is coated with said oils. This endless belt passes over two main rollers located at o )posite ends of a suitable frame, one of suc rollers being rather higher than the other so that the part of the belt 1 ing between said rollers has a downward s o )e in the o )posite direction to thetravel of t ie' belt. nto this belt towards the higher main rollers, the ore in a more or less finel divided state together with water is fed a( vantageously'in a stream, so that the wet pulp flows down towards the lower main roller and ultimately falls off the traveling belt at this point and carries with it the gangue as tailings while the metallic minerals from said wet pulp have been retained by the aforesaid oil on the belt and are recovered, all as will be more fully hereinafter disclosed.

Referring to the accom ianying drawings forming a part of this-specification, in which like numerals refer to like parts in all the views :--Figure 1 is side View in elevation of a complete apparatus according to my present invention. Fig. 2 is a plan of Fig. 1. Fig. 3 is an end view looking in the direction of the arrow 2 Fig. 1. Fig. 4 is a local view on the lines y looking in the direction ATEN Specification of Letters Patent.

of the arrow .1: Fig. 1 of one form of roller 'i.- e.

a cam roller or eccentric roller for raising and V struction of the bath or holder for the oil (or 7 7 other tack substance to be a plied to the belt) namehy a separate holder or the oil be-- fore it has been applied to the traveling belt and a separate holder for the oil after same has been removed from the belt with any metallic mineral therein. Fig. 8 is a local view on an enlarged scale showing suitable means for elevating or lowering one end of the table or frame carrying the endless traveling belt.

v1 is main roller at the higher end of the table and 2 is main roller at the lower end of the table (illustrated in'Fig. 1) hereinafter referred to as the main'rollers 1 and 2. x

3 is the endless belt (advantageously made 35 of canvas) traveling in the direction of the arrow to Fig. 1, which belt passes around the main roller 1 thence along under the roller 4 which keeps said belt 3 pressed down against the scraper blade 5 (see Figs. 1 and 7) b which latter the oil on the surface :of said be t 3 (or any desired portion thereof) is scrsgied off and drops into the oil reservoir or ta 6 which in the case illustrated in Figs. 1 and. 6

is the oil bath from which the belt is re-oiled 1 I or in the arrangement shown in Fig. 7 this tank or oil receptacle 6 is a separate receptaclc which receives therein such scraped off oil-as hereinafter explained, while the fresh oil supply for spreading on the belt is taken wise so as to put more or less pressure from the scraper 5 upon the belt 3 or from the belt 3 upon the scraper. I After passing the i i t Q2 aeamo 8 advantageously being vertically adjustable in its bearings as for example 1) means of ad ustable bearings as indicator in dotted lines in Figs; 6 and 7. The belt 3 after pass- ;'ing the oiling roller 8 and having been thor-- poses.

- oughly oiled then passes under t-he'roller 9 (or the latter may be dispensed with) and over the doctor or scraper 10 which latter-is advantageously adjustable so that any do sired amount of the oil spread on the belt by the roller 8 can be scraped off by the doctor or scraper 10 i. 0. so that exactly the desired thickness or quantity of oil required on the belt can be left thereon. After passing the scraper 10 the belt next passes over the polygonal roller 11 (Fig. 6 which may advan ta eously be an octagonal or hexagonal roller as illustrated; said iolygonul roller 11 being adjustable so as to ac forced with the desired amount of pressure against the oiled surface of the belt 3 as it passes said roller which latter is thereby rotated or may be independcntlv ('2'. e. mechanically) rotated so that as each list side of said roller ll'moves away from the belt 3 to which it tends to stick thereby the oil surface is abraded or rendered ragged or uneven by the drawing apart of the ()li surface and roller surface thus forming a roughened or uneven oil surface very suitable for my purpose namely so as to present as much oil surface to the materials '(metallic minerals etc.) which-later on are passed over same. ()r in place of the polygonal sided roller 11 I may em loy a fluted roll (either with or without tie doctor or scraper 10) such for instance as the lluted roller 11 shown in Fig. 7 whereby any surplus oil can be squeezed oif the belt and the surface of the oil layer fluted and corru ated or otherwise roughened for the aforesairfpur- Or if desired 1 may use other similar devices for the aforesaid purposes. The belt having been thus oiled then passes on round the lower main roller 2 and over any desired number of wabbling rolls 12 (see Fig. 4) three such rolls being shown in Fig. 1 or the belt 3 passes over one or more tap ing rolls 15 (see ig. 5), which are provided with a number of radial arms 13 which impart a rapid vertical vibratory action or tapping on the underside of the belt which serves to assist in bringing the mineral particles in contact with the oil on the belt.

Over the top of the belt I arrange one or I more aprons 14 which may be of matting or canvas etc. which is secured over the beltfor example by the strings 14" as shown in the drawings-in suchwise that the underside of" each apron or matting 14 will lie in the path of travel of the wet pulp lowing along the belt 3 with the result that the mineral particles of the wet pulpwill thereb be thorou hly brought into contact with t ieoil on the lieit. ()r in place of or in addition to the aforesaid a )ron 14 of flexible material I may use any ot ier suitable material such for example as a. wire gauze or grid 15 as indi, In additron to the water eated in Fig. 2. sprayer water supply employed at' the upper end of the belt I also find it advantageous-to;

em loy another water spray'i 7 at the lower our of the belt in or about the position shown m Fig. 2 with the water directed against the flow of the wet pulp along the belt 3.

Fig. 8 is an enlarged view of the rack and )inion arrangement by which that end of the irame 18 which carries the lower main roller 2 can be raised and lowered b rack and pinion motion as indicated in this figure and Figs. 1 and 2.

The various moving arts of the machine are driven by any suite. 1e means such as by belt and spur gearing as indicated in the drawiiws as will be readily understood and which driving mechanism need not therefore be here further described.

An edging is provided along each side edge flowing oil the belt lateraliv such edging either being provided on the beltitself or this edging may be formed and arranged to act as indicated in the-drawings namely by means of two separate edging belts 19 passing rdund pulleys 20 at each end of the machine so' that as the belt 3 passes along the 11- )per part of the table these edging belts orm raised edges 19 to said belt 3 {see Fig. 4') and thereby prevent the wet pulp flowing oil the same laterally.
